' STEAM-PIPE SYSTEM.

Specification of Letters Patent.

Application med January 25, 1917. Serial No. 144,360.

To all whom t may concern: y

Be it known thatI, LORIN W. BARGER, a citizen of the United States, residing-at Philadelphia, in the county of IPhiladelphia and Stateof Pennsylvania, have invented new and useful Improvements in Steam-Pipe Systems, of which the following is a full, clear, and exact description.

My invention relates toA improvements in the pipe system for supplying steam to and exhausting steam from the cylinders of ar'- ticulated lgeared locomotives.

The object of my invention is to provide a system of pipes for supplying and exhausting steam to and from the cylinders on the trucks of locomotives which does not subject said pipes to torsional strains, in which a part of the system is rigidly supported by the-underframe of the locomotive and a part is flexibly supported by the trucks, in such manner as to accommodate the swiveling or turning of the trucks on their centering devices without affecting the functions of the various pipe elements of the system.

In the drawings:

Figure 1 is a side view of a locomotive in dotted lines showing my improved system applied thereto.

Fig. 2 is a longitudinal central section. through portions of the underframe of the locomotive and trucks that support the same, drawn to a larger scale.

Fig. 3 is a transverse section of the same taken on dotted line 3 3, Fig. 2.

Fig. 4. is a horizontal section taken on dotted line #1 -4, Fig. 2.

Referring to the drawings, A, A, represent the channel-beam side-sills of the underframe of a locomotive; B, B, parallel transoms connecting the same over the centers of the front and rear trucks; a, a, tubular center-castin which are suitably secured to the lower nges of each pair of said transoms, and o, c, tubular center cast-V ings which are mounted on the bolster element d ofthe trucks C, C.

This tubular construction of these centeri ing elements around the axis of which the trucks swivel is very convenient, but is not absolutely necessary, and is adopted to permit of the passage therethrough of a downover the axle wardly extending pivotal pipe-section 5 of the steam supply lead of my improved system.l The upper endof this pivotal section 5 is connected by an elbow 6 to a transverse plpe-section 7 and the outer` end of the latter extends out through, say, the ri ht-hand side-sill and is connected by an elow 8 to the longitudinally disposed pipe-section 9.

The foregoing description of the construction of the steam pipe lead is confined to the part of my improved system which is supported by the underframe, and is aplicable to both the forward and rear truc s. The longitudinal sections 9 lof each lead extend longitudinally toward a point intersected by the transverse vertical plane of the dome D of the boiler E where they are suitably connected to the horizontal branches of a suitable T-coupling 10 by means of which they are connected to the lower end of the single vertical trunk 12 of said steam pipe, which is greater in diameter than said pipes 9 and is connected to and leads downward from dome D.

The longitudinal sections 9, 9, are each provided with a suitable valve 13, that is adapted to regulate the steam pressure flowing into the same. These valves are, preferably, located adjacent the coupling 10, but it is apparent they may be located anywhere along the length of said section.

The lower end of each pipe-section 5 is connected by a ball-joint or universal-joint 14 to the contiguous end of longitudinally A extendin central sections 15, which latter bent upward as they pass of the car-wheels e and have their ends farthest from pivotal sections 5 connected by means bows 16, the downward turned lends of which latter are connected to the center of length of a transverse bridge 17 connecting the steam-chests 18 of the cylinders 19 0n opposite sides of the truck.

he ends serted: in the slip-joints have a limited are, pre erabl amount of reciprocable play, and when the truck swivels on itsaxis this recprocable movement and the ability of its front end to swivel on the axis of pipe-section 5 avoids any displacement of the latter.

of slip-joints 20 to elof pipe-section 15 lthat are in# The mterior of bridge 17 is divided by .connected to .the adjacent ends of the longi-` tudinally extending exhaust-pipesy 24 con-- nected thereto by means of slip-joints 25.

The forward end of exhaust-pipe 24 of theA forward truck terminates and is connected by a ball-joint26 to a nipple 27 that: connects it to the lower end of an elbow 28' on the lower end of a vertical extension 29 of the exhaust pipe. This vertical .extension 29 is located in front of the pivotal members of the forward truck, and its upper end terminates in front of transoms B of thev underframe where it is connected by a forwardly bending elbow.

' Exhaust-pipe 24 ofthe rear truck extends rearwardly from bridge 17 and its rear end terminates under the pivot of the truck where it is connected by a ball-joint 31 to the vertical extension 32 of said exhaustpipe. This extension 32 extends upward throughthe tubular center casting of the rear truck immediately to the rear of and parallel to the pivotal axis of the same, and its upper end, which terminates between transoms B', B', is connected by a laterally turned elbow 33 to atransverse pipe-section 34. This pipe-section 34 extends in the direction opposite the transverse pipe-section 7 of the steam pipe lead, out through the side-sill of the underframe, and its outer end is connected by a forwardly turned elbow 35 to a comparatively long longitudinally extending exhaust-pipe section 36, which latter at its forward end is connected by a transverse pipe-sectionl to the base 30 of the exhaust-nozzle.

It will be noticed that the sections of pipe of my improved system that are supported by the underframe are immovable while the pipe-sections of the part of the system supported by the trucks are flexible, and will,

as the trucks swivel on their axes, auto-` matically accommodate themselves to any change of position thereof withrelation to l stationary pivotal pipe-sections 5 andthe vertical extensions 29 and 32 of the exhaust-pipe without altering their relations or a'ecting their respective functionsy of supplying steam to the cylinders and conveying the exhaust steam therefrom.
